Specification of Letters Patent.

Patented Nov. 14, 1916.

Application l'ed Mayl, 1916. Serial No. 97,825.

To all whom t .may concern Be it known :that I, MARION G. Norms, acitizen of ther` United States, residing at Pond Creek, in the. vcountyyof Grant and State. of Oklahoma,.have invented certain new and usefulImprovements inv-Wrenches; andi do hereby declare the following to beaofull, clear, and exact' description ofthe invention, such as willenablenothers skilled in the art to which it appertainsto make and usethe same.

Myy invention', relates to new and useful improvements inv wrenches4 andisy particularly adaptable for rotating pipes, bolts, nuts, and thelike, .and my `Objectis to-provide a hollow handle Sectionftowhich-isyattached a fixed jaw.

A further object' is-to providea jawI for cooperating with thexedjaw andslidably mounted in they handle section.

A, further object is'to provide; a lever adapted .to cooperate-with theshank-'ofthe movable jaw' for holding the samein adjusted position.

A further object; is: to A@provi-del ay screw driver at the free end ofthe lever. And a further object istozprovide means for normally holdingthe lever in fixed position in line with or at right angles to thehandle section whereby said handle section=may vbe used for rotating theleverl whenused as a screw driver.

Other objects and advantages will be hereinafter seti; forthJ andmoreparticularlypointed out in the accompanying specica-f tion.

In the accompanying drawings which are made a part of this application,Figure 1 is a longitudinal sectional view of the wrench showing the jawsand operating lever therefor in side elevation. Fig. 2 is a transversesectional view as seen on line 2-2 of Fig. 1. Fig. 3'is a similar viewas seen on line 3 3 of Fig. 1, and Fig. 4 is a similar view as seen online 4-4 of Fig. 1.

Referring to the drawings in which similar reference numerals .designatecorresponding parts throughout the several views, 1 1ndicates the handlesection which is preferably rectangular in cross section and hollow, aportion of the end wall of the handle section being removed to form anOpening 2 for the reception of a movable jaw 3, said movable jaw havingashank 4 adapted to slide lengthwise of the handle section, the

length of the-shank being substantially onehalf the length-of the bodyportion. Thel movable jaw 3 is held in perfect alinement with the handlesection by extending apin 5 transversely of the movable jaw, the ends ofthe `pin being entered in slots 6 in the side walls of the handlesection. 4

Cooperating with the movable jaw 3 is a fixed jaw 4, one end of which isentered through the opening 2 between the side walls of the ,handlesection and at one end thereof, the end of the jaw entering the handlesection having a seat or shoulder 8 which engagesthe top'wall of thehandle section, said jaw beingsecuredf to the handle section byextending rivets 9 transversely through the side-walls of the handlesection and through the interposed portion ofthe fixed jaw.

Oneedge of the shank is provided with a plurality of notches 10 withwhich engage teeth 11 carried bythe lever 12, said lever having acircular head 13 at its inner end through which extendsa pivot 14,the'adj acentend wall of the handle section being removed topermit thelever to readily swing intoalinement with the handle section and shankor at right angles thereto,'the pivot 14 extending through the sidewalls of the handle section ata point between the ends of the handlesection. One facewall 15 of the notches is at right angles to the trendof the shank, while the opposite wall 16 of each notch is preferablyS-shaped or composed of two oppositelyextending curves,l

while the wal/ls 17 of the teeth 11 are likewise at right angles to thetrend of the lever and the walls 18 thereof 'similarly curved to thewall 16 of the notches 10, the straight walls of the notches and teethcooperating with each other to-hold the movable jaw in fixed position,while the curved walls of the notches and teeth permit said teeth toreadily enter Or leave the notches.

The end of the lever 12 is extended a distance beyond the end of thehandle section 1 and is preferably provided with a screw driver point19, and in order to hold the lever in alinement with the handle section,or at right angles thereto so that the handle section may be used as alever or handle for rotating 4the lever when used as a screw driver, thecurved face of the head 13 is provided with recesses 20 and 21 withwhich is adapted to engage a spring detent 22 fixed to the adjacent endwall of the handle section l, the free end of the detent extendingbetween the side walls of the handle section so that when the lever isin alinement with the handle section or in the position shown in Fig. l,the end of the detent will be in engagement with the recess 20, whilewhen the lever is swung to right angles to the handle section, Athedetent will engage the recess 21 and hold the same against lateralswinging movement while the lever is being used as a screw driver, thehandle section l serving as a cross head or handle for rotating thescrew driver and said detent will also serve to hold the lever in fixedposition and out of alinement with the shank while the movable aw isbeing adjusted.

The meeting faces of the jaws 3 and 7 are preferably provided withserrations 23 and 24 respectively on the portions thereof projectingbeyond the handle section so that a round object, such as a pipe, bolt,or the like, may be readily rotated by the wrench.

In applying this form of wrench to use, the lever l2 is swung outwardlyuntil the teeth 1l are out of engagement with the notches 10 and theobject to be rotated positioned between the jaws 3 and 7 when the leveris again swung inwardly and the teeth thereon entered in correspondingnotches in the shank 4C, the inward swinging movement of the leverforcing the movable jaw into engagement with the object between the jawsand by providing theV spring detent, the jaw 3 will be held againstmovement in either direction until the teeth l1 are again disengagedtherefrom. The object in projecting the free end of the lever beyond theend of the handle section not only permits the lever to be used as ascrew driver, but said projecting end can be readily grasped forreleasing the teeth 11 of the lever from the notches lO of the shank.

This form of wrench can be very cheaply constructed and may be made invarious sizes as occasion may require and as all the parts areconstructed of metal, it will be practically indestructible from use. Itwill also be seen that the wrench structure may be used in viseformation for holding articles of various kinds and by extending thefree end of thelever 12 beyond the end of the handle section, theprojecting portions of the lever may be readily grasped for swinging thelever on its pivot for disengaging the teeth from the notches.

Having thus fully described my invention 4what I claim as new and desireto secure by gage the said recesses, said detent when engaged in one ofsaid recesses serving to hold the lever in locked engagement with themovable jaw to prevent movement of the movable jaw with respect to thefixed jaw.

In testimony whereof I have lsigned my name to this specification in thepresence of two subscribing witnesses.
